PURSUE Record — PURSUE Case PR-035: Greece 2023: U.S. Department of War / AARO · Infrared sensor, 24 sec. European Command encounter, unresolved. | Unresolved ·

PURSUE Case PR-035 is a 24-second military infrared sensor video recorded in Greece in 2023 and formally released by the U.S. Department of War and the All-domain Anomaly Resolution Office (AARO) on May 8, 2026 as part of PURSUE Release 01. The case is classified as unresolved — meaning analysts did not reach a conclusive identification of what the sensor captured. It is one of 28 video records in the release and one of several originating from European theater operations.

What this record contains

The public release catalogues this record as a single-file video (VID) captured via infrared sensor, running 24 seconds in duration. The releasing agency is the U.S. Department of War coordinated through AARO, the office congressionally chartered to collect, analyze, and resolve UAP reports across military and intelligence domains. The incident is dated to 2023 and attributed to European Command — the combatant command responsible for U.S. military operations across Europe, including Greece and the broader Eastern Mediterranean. The official description characterizes it as a "European Command encounter, unresolved." No additional metadata beyond these parameters is included in the public release for this record. The full source file and release catalogue entry are available on the SkyLens UAP files page.

The public release does not include witness accounts, platform identification, sensor altitude, or target range data for PR-035. What is documented is the sensor modality (infrared), the duration (24 seconds), the geographic command area (European Command), and the resolution status (unresolved).

Sensor & operational context

Infrared sensors detect thermal radiation rather than visible light, imaging objects by the heat they emit or reflect. Military IR systems — whether mounted on aircraft, drones, or fixed surveillance platforms — are optimized to track heat signatures: engine exhaust, aerodynamic friction, or the thermal contrast of an object against a cooler background sky or sea. This sensitivity makes IR video particularly useful for tracking fast or high-altitude objects in conditions where visible-spectrum cameras would fail, but it also introduces specific interpretive challenges. Atmospheric temperature gradients, sensor bloom from bright thermal sources, and the lack of visible surface detail mean that IR footage often captures shape and motion but not texture, color, or fine structure. Size and distance are difficult to determine without independent ranging data, which may or may not exist for this record.

The Eastern Mediterranean — the operational region covered by European Command that includes Greece — is an active zone for U.S. and NATO intelligence, surveillance, and reconnaissance activity. The area sees regular aerial operations, naval movement, and sensor coverage from multiple allied platforms. A 2023 encounter in this region would have occurred within a mature ISR infrastructure, meaning the original analysts likely had access to corroborating radar or signals data. Whether such corroborating data exists for PR-035 is not stated in the public release.

What this does and does not prove

What the record documents is that a U.S. military infrared sensor captured something over or near Greece in 2023 that AARO analysts did not resolve to a known identification before the May 2026 release. "Unresolved" is an analytic status, not a finding of anomaly. It means the case remained open — not that the object was extraordinary, not that conventional explanations were ruled out, and not that any specific hypothesis was confirmed. The 24-second clip may contain clear motion data, may be ambiguous, or may have degraded signal quality; the public release does not specify. Readers should treat PR-035 as an unidentified item in an official inventory, with the honest caveat that absence of explanation is not evidence of anything beyond the limits of available data.

How it fits PURSUE Release 01

PR-035 sits within the contemporary military sensor tier of PURSUE Release 01 — the subset of the 162-document release drawn from recent Department of War operational reporting rather than the FBI historical files dating to 1947 or the NASA archive imagery from crewed spaceflight programs. This tier is directly relevant to the active AARO mission: current-generation sensor data from credentialed military platforms, reviewed by trained analysts, and released to the public when resolution could not be reached. Alongside other unresolved video cases in the release, PR-035 contributes to the documented picture of what the U.S. military's sensor network is encountering and has not yet explained.
